Request: Gmail search contacts & compose

[mnisbet]

The plugin at http://bit.ly/129oQLQ is great for those that store all their contacts in their computers address book. I only use my computers address book for close contacts and gmail stores all the others online. Would it be possible to autocomplete the contacts email by searching contacts stored in gmail?

 

Also, the ability to add multiple contacts separated by a comma such as at http://bit.ly/10MqgSm would be useful.
